Alstroemeria plant variety named `Stadelil`

ABSTRACT

A new and distinct Alstroemeria plant variety producing flowers of good quality and attractive coloration.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety ofAlstroemeria originated as a seedling by crossing as seed parent anunreleased, unpatented seedling identified as 86R776-1 and as pollenparent an unreleased, unpatented seedling identified as 87G737-2 fromamong my collection of Alstroemeria seedlings maintained undercontrolled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer,The Netherlands, for developmental purposes. The varietal denominationof the new variety is `Stadelil`.

The first act of asexual reproduction of `Stadelil` was in Aalsmeer, TheNetherlands, by propagation by dividing rootstocks. Asexual reproductionthrough successive generations has demonstrated that the combination ofcharacteristics as herein disclosed for `Stadelil` are firmly fixed andretained through successive generations of asexual reproduction.

`Stadelil` has not been observed under all possible environmentalconditions. Phenotypic expression may vary with variations inenvironment such as temperature, light intensity, day length and growingand cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Stadelil` are characterizedby flowers of unusual coloration, as described herein.

The new variety blooms profusely with good annual production, includingproduction of flower stems in winter under greenhouse conditions in TheNetherlands, which is a desirable characteristic in a cut flowervariety. `Stadelil` grows productively under greenhouse conditions andis also reproducible both by division of rhizomes and by tissue culture.
